Said jacket .comulative. adjustment between said grooved memprises the upper and lower members (32') and be!" and said ports provided in the base of said (33) respectively, said upper member is flanged jacket and leading to said nozzles. downwardly at (34) to engage the upwardly disposed flange (35) by screw-threads as (36). Obviously, said members may be otherwise secured together, as by lugs and bolts.

The neck (3'7) rises concentrically from the member (32), is counterbored to provide the annular water-space (38) surrounding the adjacent portion of the reduced axle (23) which has perforations as (39) adapted to provide water Ways establishing communication between the stem (20) and the jacket R. The upper portion of said neck is reenforced and bored to be a turnable fit on the portion (24) thus providing a seat for the nut (40) when screwed on to the threaded portion (25), and locked in adjustment by the nut (41). By varying the level of said nuts (40) and (41) the space can be increased or diminished to suit varying pressures and thereby attain straight line sprinkling between the peaks P, P1, P2, P3.

The upper end of said neck is externally threaded at (42) to match the internal thread (43) of the packing nut (44) suitably bored out to clear the nuts (40), and (41). ihe packing washer (45) is inserted between the upper surface (46) of said reenforcement and the annular surface (47), thereby providing a water-tight joint to prevent leakage upwardly from said jacket.

The nut (44) is diminished diametrally above the area of said washer and rises cylindrically to the closure (48) which is centrally bored and tapped to accommodate the adjustment screw (49) having the head (50) adapted to contact against the upper end of the threaded portion (25), said screw being provided with the slot (51) and the lock nut (52).

Said screw provides means for vertical adjustment of the head (50) against the upper end of the portion (25) to support the weight of the revoluble elements D and to provide regulable adjustment between the member (33) and the grooved member (28). The lower jacket member (33) is adapted to slip upwardly on to the axle (20) and is jour naled thereon by the neck (53) which is suitably threaded to engage threads (54) in the follower packing-gland (55); the packing washer (56) intervenes between said neck and said gland. When so disposed said members are then screwed tightly together as illustrated in Figure 1.

It will be noted in Figures 2, 4 and 6, that the present sprinkler is shown as having three nozzles, but the number could be varied, without departing from the spirit of the invention.

Figures 1 and 4 show threaded sockets as (57) adapted to receive threaded ends as (58) of said respective dispensing arms, or nozzles. Said sockets are cast integrally with member (33) and project downwardly below the plane thereof, and are set 120 degrees apart.

As the present embodiment of my sprinkler is designed to water a square area, I provide four radial grooves, (59), (59), (59") and (5911), set 90 degrees apart on the under side of the member (28).

Reference being had especially to Figures 3 and 7; it will be apparent that each quadrant of said grooved member has a radial ridge (60) at its center, and that each such ridge lies in the same plane as the inner surface of the member (33) Ports (61) (61') and (61) are provided transversely of the member (33) being arranged for passage of water from said jacket to the respective nozzles.

Having reference to Figure 2, it will be noted that the dispensing nozzle (29) registers fully with the port (61) which is assumed to be throwing a peak jet (P1) while the device D revolves counter-clockwise; in this position the nozzle (31) is throwing a gradually diminished jet while departing from the groove (59a), whereas the nozzle (30) is throwing a gradually increasing jet as it approaches full registry with the groovej(59): said respective grooves and ridges being so adapted and arranged that the augmented and diminished jets cover a straight line between peak and peak, thereby watering a square area.

It will be noted that as an equalizing means to get the same pressure in the jacket above and below the member (28) the member 33) is counterbored at (62) and the adjacent portion of the axle (20) has the perforations (63) communicating therewith.

In the operation of my device, when water is turned on at the valve (64), Figure 5,water will be dispensed through the perforations "(65) of said nozzles; this will cause the sprinkler to rotate counter-clockwise, causing Water to be distributed with varying force from the respective nozzles according to their proximity to any one of said grooves in the member (28).

It is believed that my invention and the ad vantages to be gained by the use thereof are fully explained. In reducing the invention to practice, certain minor features in construction, combination and arrangement of parts may necessitate alteration, to which the patentee is entitled, providing such alteration is comprehended in the scope of what is claimed.

What I claim is:--

In a device of the kind described, a tubular axle, a disc-like member secured substantially midlength of and at right angles to the axle, a plurality of radial grooves formed on the under side of the disc, said grooves separated by ridges; a

water jacket comprising a lower and an upper member forming a chamber enclosing said disc like member, a concentric neck extending downwardly from said lower member and journaled on the axle, a packing gland and packing engaging said neck and axle; a counterbore in said neck adjacently below said disc-like member and communicating with said grooves, perforations in said axle communicating with said counterbore; a concentric neck rising from said upper jacketmember and journaled on the axle, a counterbore in said upper neck open to the chambenperforations in said axle leading to said upper counterbore and chamber; said axle comprising a solid upper end of reduced diameter protruding upwardly beyond the upper end of said upper neck, said solid portion screwthreaded,'a nut engaging said threads and arranged to react against the upper end of said neck, a lock-nut carried'by said threaded portion above the former nut; a packing gland and packing engaging said upper neck and axle, a concentric, vertically-disposed adjustment screw mounted in said gland and arranged to react against said axle end, and means to lock said screw; a plurality of reaction nozzles carried by the lower water jacket member, a port leading from the base of said lower jacket mem ber to each said nozzle, the said ports successively cooperative with said grooves and ridges when under impellance.
